Research Interest

Dr. Mopidevi is interested in understanding molecular mechanisms and the role of single nucleotide polymorphisms in the regulation of blood pressure and hypertension using humanized transgenic mice, microRNA function, DNA methylation and epigenetic regulation.

Hypertension is a serious risk factor for myocardial infarction, heart failure, vascular disease, stroke, and renal failure. Like other complex diseases, hypertension is caused by a combination of genetic and environmental factors. It has been estimated by segregation analysis and twin studies that approximately 45% of the inter-individual differences in blood pressure can be accounted by genetic differences. However, molecular mechanisms involved in pathophysiology of hypertension are not clear.

Aldosterone synthase, the rate limiting enzyme in the biosynthesis of aldosterone, is encoded by Cyp11B2 gene. This gene is expressed mainly in adrenal cortex and to some extent in kidney, brain, ­and adipose tissue. The epidemiological studies have suggested that -344T/C polymorphism is shown to be associated with increased aldosterone level and increased blood pressure. The hCyp11B2 gene has 3 SNPs in 1 Kb of its promoter and these polymorphisms are in almost complete linkage dis-equilibirium. These SNPs are rs1799998 (T/C at -344), rs10087214 (C/T at -470), and rs28659182 (C/A at -663). Thus variant -344T almost always occurs with variants -470C and -663A (named haplotype-I), and variant -344C almost always occurs with variants, -470T and -663T (named haplotype-II) in human subjects. In order to understand the physiological role of these haplotypes on transcriptional regulation of hCyp11B2 gene and blood pressure regulation in an in vivo situation, we have generated transgenic mice by knocking in hCyp11B2 gene containing either haplotype-I or haplotype-II at the HPRT locus. Currently our group actively engaged in studying the molecular mechanism by which these promoter polymorphisms alter the binding of the transcription factors and regulate the blood pressure. Further we have extended our research interests to micro RNA and shown that the microRNA miR-31 and miR-584 bind strongly to the human angiotensinogen (hAGT) 3'UTR containing 11525C-allele as compared to 11525A-allele and down-regulate the hAGT mRNA and protein levels in human liver cells. These studies not only provide new insight into understanding the molecular basis of hypertension, but will also have significant clinical relevance to develop new therapeutic strategies for hypertension.
